Without pics it's tough to grade with certainty. That phone board should be on the high end of mid-grade most likely and you should expect between $1.50-2.15/lb for it if that's right. The keypad and display boards it really depends. If the display screen is still attached that's a low grade board for everyone. If you removed the display you can normally mix them in with mid-grade even though the epoxy hinders material recovery from the IC chips underneath them. If the keypad board has gold trace contacts you might find someone to give you more than low grade, if not then low grade.
